Sheet fastening assembly and fastener therefor

Abstract

A sheet fastening assembly is disclosed for releasably securing sheets to an object. Included in the assembly is an anchoring device, an interconnecting device and a sheet fastener. The sheet fastener includes a sheet grasping member which is slidable within a slot defined by a clasping member of the fastener for releasably securing sheet material therebetween. The slidable sheet grasping member is provided with locking tabs for releasably locking the slidable member in a sheet engaging position.

What is claimed is: 
     
       1. A bedsheet fastening assembly comprising: an anchoring means for anchoring a sheet fastening means to an underside of a mattress;   sheet fastening means for releasbly grasping a bedsheet;   said fastening means including a clasping member having a bedsheet receiving slot and a slidable sheet grasping member including projection means for releasably sliding within said slot and for releasably grasping the bedsheet therebetween;   interconnecting means for interconnecting said anchoring means to said fastening means;   said projecting means includes a neck portion and a relatively enlarged button portion extending from said neck portion, said projecting means being sized and shaped to allow the bedsheet to be fitted over said button portion and to fit in said slot as said projecting means slidably moves in said slot, said neck portion being slidable within said slot and allowing the bedsheet to be accommodated between a bottom of said button and said clasping member;   said interconnecting means is elastic and facilitates said assembly accommodating different sized bedsheets;   said grasping member is a thin and flexible member and having locking projections which lockingly engage locking slots formed in said grasping member;   said locking projections project laterally from said neck portions for releasable engagement with said locking slots formed in portions of walls defining said bedsheet receiving slot;   said grasping member has retaining tabs extending therefrom;   said grasping member has split retaining legs;   said clasping member has recesses which slidably engage projections on said split retaining legs; and,   said sheet grasping member is mounted for slidable and tiltable movement on said clasping member wherein said projection means can move between a position adjacent a top surface at said clasping member to a position adjacent a bottom surface of said clasping member to facilitate grasping and releasing of the bedsheet.   
     
     
       2. A sheet fastener comprising: a clasping member having a sheet receiving slot; and,   a slidable sheet grasping member including projecting means for releasably sliding within said slot and for releasably grasping the bedsheet therebetween; said projecting means includes a neck portion and a relatively enlarged button portion extending form said neck portion, said projecting means being formed to allow the bedsheet to be accommodated between a bottom of said button and said clasping member, to allow the bedsheet to fit over said button and within said slot, and to allow said grasping member being able to slidably and snugly engage the bedsheet resting on an opposite surface of said clasping member;   said grasping member is a thin and flexible member and has locking projection which releasably lockingly engage corresponding locking slots formed in said clasping member;   said locking projections project laterally from said neck portion, and said locking slots are formed in wall portions defining said sheet receiving slot;   said grasping member has retaining tabs extending therefrom;   said grasping member has split retaining legs;   said clasping member has recesses which slidably engage projections on said split retaining legs;   said clasping member has recesses which slidably engage projections on said split retaining legs; and,   said sheet grasping member is mounted for slidable and tiltable movement on said clasping member wherein said projection means can move between a position adjacent a top surface at said clasping member to a position adjacent a bottom surface of said clasping member to facilitate grasping and releasing of the bedsheet.
